As for "stupid combotastic win con", that's what Rogue does best, whether you like it or not. Ideally, you use Deadly Poisons and/or Tinker's Sharpsword Oil on the Blade, smack the opponent in the face a couple times, then finish with a Blade Flurry, (plus whatever other damage you have available). If you don't like playing that way, Rogue may not be your cup o' tea.
